Expertise integration can be defined as ‘the synthesis of individual team members’ information and expertise through social interactions’ (Robert et al., 2008). Researchers relate integration to the process of coordinating special expertise held by individuals or moulding individually held information and know-how into a common stock of knowledge to solve problems and accomplish tasks at the project level (Newell et al., 2000; Tiwana & McLean, 2005; Mitchell & Nicholas, 2006; Yoo et al., 2007).
